legend.textStyle. lineHeight 无效

Version

5.1.2

Reproduction link

https://echarts.apache.org/zh/option.html#legend.textStyle.lineHeight

Steps to reproduce

在最新的官方文档示例中：https://echarts.apache.org/zh/option.html#legend.textStyle.lineHeight
设置“legend.textStyle.lineHeight = 80”不会生效，但是如果设置了 “legend.textStyle.backgroundColor = 'rgba(251, 114, 114, 1)'"，lineHeight属性就会生效

不生效的配置：

  legend: {
    textStyle: {
      lineHeight: 80
    }
  },

生效的配置：

  legend: {
    textStyle: {
      lineHeight: 80,
      backgroundColor: "rgba(251, 114, 114, 1)"
    }
  },

在旧版本api中设置则没有出现这个问题

What is expected?

单独设置legend.textStyle.lineHeight生效

What is actually happening?

单独设置legend.textStyle.lineHeight不生效，必须要设置一个legend.textStyle.backgroundColor背景色

TITLE

legend.textStyle. lineHeight is invalid

BODY

Version

5.1.2

Reproduction link

https://echarts.apache.org/zh/option.html#legend.textStyle.lineHeight

Steps to reproduce

In the latest example of official documentation: https://echarts.apache.org/zh/option.html#legend.textStyle.lineHeight
Setting "legend.textStyle.lineHeight s 80" does not take effect, but if you set "legend.textStyle.backgroundColor s'rgba(251, 114, 114, 1)'," the lineHeight property takes effect

Configurations that do not take effect:

  legend: {
    textStyle: {
      lineHeight: 80
    }
  },

Configuration in effect:

  legend: {
    textStyle: {
      lineHeight: 80,
      backgroundColor: "rgba(251, 114, 114, 1)"
    }
  },

This problem does not occur when set in an older version of api

What is expected?

Set legend.textStyle.lineHeight separately to take effect

What is actually happening?

Setting legend.textStyle.lineHeight separately does not work, and you must set a legend.textStyle.background Color background color
